I have a client who complied with all IRS 1031 real estate exchange requirements in 2020 but was prevented from completing the exchange because of the pandemic when the lender on the replacement property pulled out at the last minute and no one else would make the loan because of the pandemic. I prepared his return reporting the sale and gain and we attached a letter explaining why he requested a waiver of the gain due to the Covid emergency. Needless to say both his State and the IRS are still requesting the substantial capital gains amount. When my client attempted to appeal the request to his State he was informed that there is a statute that says a taxpayer can't appeal something on his own return that he reports he owes and can only appeal determinations of assessed amounts from the State, as from an audit for example.
So now my client wants to submit an amended return reporting the gain but somehow also reporting on the return that no capital gains tax is owed because CV19 prevented its completion, so at least when the amended return is submitted and the IRS or State still want a payment it's based on their determination and can therefore then be appealed. Looking for the best way to do this on the return. I've thought of somehow characterizing it as a casualty loss or something similar but I'm still not certain of the best way or if there is a way to accomplish what I need. Any suggestions or ideas would be appreciated.
